Description

Audience rating survey system and method {SYSTEM AND METHOD FOR MEASURING PROGRAM RATING}

The present invention relates to an audience rating survey system and method, and more specifically, to a viewership rating survey system and method that can generate viewing information about which broadcast is being watched by obtaining sound sources from users watching a broadcast. .

As IPTV services expand, the need to more accurately measure viewer ratings using IPTV services is increasing.

This is because broadcasters can determine what kind of content viewers want, and advertisers can verify the validity and effectiveness of advertising costs.

It is also used as important data in determining advertising prices.

Conventional IPTV service is a medium that requires large-capacity communication. Data packets required for the IPTV service are transmitted in both directions between the server side and the subscriber side (set-top box), with most (about 99%) of the downstream traffic from the server. It accounts for a very small portion of traffic (approximately 1%) and upstream traffic to the server side.

Therefore, analyzing data packets in both directions of uplink and downlink traffic requires high-capacity, high-performance equipment and generates a lot of heat.

Therefore, rather than analyzing all uplink and downlink traffic in communication, it is necessary to detect uplink traffic transmitted from the set-top box to the server and analyze the data packets included in this uplink traffic.

To analyze one-way network traffic, you must select one of the following two methods.

(1) How to receive packets using the “port mirroring” technology of the communication equipment to which the set-top box is connected.

(2) A method of receiving and analyzing electrical signals by connecting the core wires of a pair of UTP cables connecting a set-top box to a device.

The method of (1) above is easy to implement, but cannot be applied due to the decisive disadvantage of installing additional equipment and adding additional management and introduction costs, and the method of (2) is relatively expensive compared to the method of (1). The desired goal can be achieved at low cost.

However, in method (2) above, because communication equipment and set-top boxes use “automatic media selection circuit (Auto MDI-X),” the direction of detected traffic changes or maintains an incorrect situation every time a connection is established. There is a problem that problems arise.

Meanwhile, a method of mechanically determining whether TV is watched on a viewership survey device is very important.

In particular, in a set-top box-based TV viewing environment, there may be a problem where powering on the set-top box is not connected to actual TV viewing.

In other words, if the set-top box is turned on but the TV is turned off, it may be determined that the set-top box is continuously watching the same channel.

In addition, even when the set-top box is turned off, data is actually periodically exchanged internally with the IPTV service provider's server through a communication device. Therefore, whether the TV is actually turned on is inevitably key information for evaluating the reliability of viewer ratings.

Hereinafter, with reference to FIGS. 1 to 5, the viewership rating survey method and viewership rating survey system 10 implemented by the viewership rating survey system 10 of the present invention will be described in detail.

For example, the viewership rating survey method is a method for generating viewership information by examining viewership ratings for broadcasts actually watched by viewers (users), and can be implemented by the viewership rating survey system 10.

For example, as shown in FIG. 1, the audience rating survey system 10 can transmit and receive certain information with external devices.

For example, the external devices may be broadcast devices 20 that have broadcast information such as broadcast video and broadcast audio, or may be user devices 30 owned by the user watching the broadcast.

For example, the broadcasting device 20 may be a broadcasting-related server owned by a broadcasting station, and the user device 30 may be a smartphone, terminal, etc. owned by the user.

However, for convenience of explanation, the description will be made on the assumption that the user device 30 is a smartphone owned by the user.

For example, the user device 30 is a known smartphone and may include components such as a communication module capable of communicating with other devices, a microphone capable of recording sound in real time, and a timer that generates time information.

Meanwhile, as shown in FIG. 2, the viewer rating survey system 10 includes a communication unit 100 that transmits and receives information/data required to implement the viewer rating survey method to be described below with an external device, and a communication unit 100 necessary to implement the viewer rating survey method. A memory unit 300 that stores information/data, an input unit 400 that receives information/data/operational expressions/commands required to implement the viewer rating survey method from the administrator, and displays the information/data needed to implement the viewer rating survey method. It may include a display unit 500 that operates and a controller 200 that calculates/processes information/data necessary to implement a viewer rating survey method.

Hereinafter, with reference to FIGS. 3 to 5, the viewership rating survey method and viewership rating survey system 10 of the present invention will be described in more detail.

For example, the viewer rating survey method and viewer rating survey system 10 does not generate the viewing information through a survey device such as a set-top box installed on a conventional TV, but rather uses a smartphone owned by the user watching the broadcast (the user A main feature may be that the viewing information is generated through the device 30.

For example, in order to implement the viewer rating survey method, the viewership rating survey system 10 may provide a predetermined application to the user device 30 and provide a predetermined user interface through the application.

Below, the viewership rating survey method and viewership rating survey system 10 will be described in detail.

For example, the viewership rating research method may include obtaining a user's voice sound source from the user device 30 (S100).

Here, the voice sound source refers to a sound source for the user's voice, and may, for example, refer to a sound source for the user's voice saying “Hello.”

Here, as an example, the step of acquiring the user's voice sound source (S100) involves acquiring not only the voice sound source but also user information such as the user's age, name, address, gender, and phone number from the user device 30. You can.

The step of acquiring the user's voice sound source (S100) may be implemented by the communication unit 100 of the audience rating research system 10 receiving the voice sound source and the user information from the user device 30.

For example, the voice sound source and the user information may be stored in the memory unit 300.

Meanwhile, the viewership rating research method may further include a step (S200) of acquiring a broadcast sound source from the broadcasting device 20.

For example, the broadcast sound source (Q) refers to a sound source for broadcast content that has actually been broadcast. In the step (S200) of acquiring the broadcast sound source, the communication unit 100 of the audience rating survey system 10 It can be implemented by receiving the broadcast sound source (Q) from the device 20.

Here, as an example, the broadcast sound source Q may include broadcast time information about the actual broadcast time.

That is, the broadcast sound source Q may include not only a sound source for actually broadcasted broadcast content, but also the broadcast time information, which is information about the broadcast time of the actually broadcasted broadcast content.

For example, the broadcast sound source (Q) may be stored in the memory unit 300.

Meanwhile, the viewer rating survey method may further include a step (S300) of acquiring a recorded sound source from the user device 30.

For example, the recorded sound source (R) refers to a sound source recorded in real time by the user device 30, and may be a sound source mixed with the sound of broadcast content played on a TV, ambient sounds, or conversations between users, etc. .

The step of acquiring the recorded sound source (S300) may be implemented by the communication unit 100 of the audience rating survey system 10 receiving the broadcast sound source Q from the user device 30.

Here, as an example, the recording sound source R may include recording time information about a recording time recorded in real time.

That is, the recorded sound source R may include not only the sound source recorded in the user device 30 but also the recording time information, which is time information when the sound source was recorded.

For example, the recorded sound source R may be stored in the memory unit 300.

Meanwhile, the viewer rating survey method may further include a step (S400) of comparing the broadcast sound source (Q) and the recorded sound source (R) to generate viewing information for the broadcast sound source (Q).

To explain this in more detail, the step of generating the viewing information (S400) is a step of calculating which broadcast the user watched among numerous broadcasts, and the recorded sound source (R) obtained from the user device 30 and the By calculating the similarity between the numerous broadcast sound sources (Q) obtained from the broadcasting device 20, it is calculated which broadcast sound source (Q) among the numerous broadcast sound sources (Q) the recorded sound source (R) corresponds to. can do.

For example, the similarity between the broadcast sound source (Q) and the recorded sound source (R) is determined by matching and comparing the fingerprints of the broadcast sound source (Q) and the recorded sound source (R), as shown in FIG. It can be implemented by doing.

To explain this in more detail, a similarity image (I) can be extracted/generated by matching the fingerprints of the recorded sound source (R) and the broadcast sound source (Q).

When the fingerprints of the recorded sound source (R) and the broadcast sound source (Q) are the same, a straight line (L) having a predetermined inclination angle may be displayed in the similarity image.

Conversely, if the fingerprints of the recorded sound source (R) and the broadcast sound source (Q) are not the same, a straight line (L) having a predetermined inclination angle may not be displayed in the similarity image (I).

Since this technical idea is disclosed in Republic of Korea Patent No. 10-2447553 B1 (2022.09.21), of which the present applicant is the patentee, detailed description will be omitted.

Meanwhile, the step of generating the viewing information (S400) involves comparing the broadcast sound source (Q) including the broadcast time information corresponding to the recording time information and the recorded sound source (R) among the broadcast sound sources (Q). You can.

To explain this in more detail, comparing the recorded sound source (R) with numerous broadcast sound sources (Q) takes a lot of load and time. To solve this, the step of generating the viewing information (S400) Only sections of the broadcast sound source (Q) having a time corresponding to the recording time information included in the recorded sound source (R) can be extracted and compared between the recorded sound source (R) and the extracted broadcast sound source (Q). .

That is, the recording time information included in the recorded sound source (R) is 2022.12.01. Recording starts at 14:00 (t1), 2022.12.01. In the case of information that recording has ended at 14:05 (t2), the step of generating the viewing information (S400) is to determine whether the broadcast time information is 2022.12 among the numerous broadcast sound sources (Q) stored in the memory unit 300. .01. From 14:00(t1) to 2022.12.01. Only the broadcast sound source (Q) section (A) corresponding to 14:05 (t2) can be extracted and compared with the recorded sound source (R).

Meanwhile, if necessary, the broadcast sound source (Q) may be extracted including a section (B) extending before/after a preset time than the time corresponding to the recording time information.

Meanwhile, the step of generating the viewing information (S400) compares the recorded sound source (R) and the voice sound source, and if there is a corresponding section in the recorded sound source (R) that is the voice sound source, the recorded sound source (R) excludes the corresponding section. The recorded sound source (R) and the broadcast sound source (Q) can be compared.

To explain this in more detail, the voice of a user whose privacy needs to be protected, such as a conversation between individuals, may be recorded in the recorded sound source R recorded in the user device 30.

Therefore, in order to protect privacy, the step of generating the viewing information (S400) includes, when receiving the recorded sound source (R) from the user device 30, the recorded sound source (R) and the memory unit 300. By comparing the voice sound sources stored in , it is possible to calculate whether the recorded sound source R includes the user's voice.

If the recorded sound source (R) has a section corresponding to the voice sound source (if there is a section containing the user's voice), the step of generating the viewing information (S400) is performed in the recorded sound source (R). Excluding the section corresponding to the voice sound source, the remaining recorded sound source (R) and the broadcast sound source (Q) can be compared.

That is, the recording time information included in the recorded sound source (R) is 2022.12.01. Recording starts at 14:00 and ends on 2022.12.01. In the case of information that recording ended at 14:05, here, the section of the recorded sound source (R) corresponding to the voice sound source is 2022.12.01. From 14:01 to 2022.12.01. If it is until 14:02 (which may mean the corresponding section), the step of generating the viewing information (S400) is 2022.12.01, which is the section corresponding to the voice sound source in the recorded sound source (R). From 14:01 to 2022.12.01. Except for the section up to 14:02, comparison can be made between the recorded sound source (R) and the broadcast sound source (Q) for the remaining sections.

At this time, the broadcast sound source (Q) is also 2022.12.01. From 14:01 to 2022.12.01. It can be compared with the recorded sound source (R) for sections excluding up to 14:02 (which may refer to the corresponding section).

Meanwhile, in the step of generating the viewing information (S400), the sound source of the corresponding section in the recorded sound source (R) may be deleted from the memory unit 300.

Meanwhile, in the step of generating the viewing information (S400), the viewing information about which broadcast the user watched can be generated by comparing the recorded sound source (R) with the plurality of broadcast sound sources (Q). .

For example, the viewing information may be information including the viewership rating for a specific broadcast, the viewer's age, gender, or region based on the specific broadcast.

Additionally, the viewing information may be information about when and which broadcast was watched based on the user.

This step of generating the viewing information (S400) may be implemented by the controller 200 of the viewer rating research system 10.

Meanwhile, the viewer rating survey method may further include providing the calculated viewing information to the external device (S500, S600).

For example, when the viewing information is provided to the broadcasting device 20, the viewing information is information including the viewer rating for a specific broadcast and the viewer's age, gender, or region based on the specific broadcast broadcast by the broadcasting station. You can.

Meanwhile, when the viewing information is provided to the user device 30, the viewing information may be information about when and which broadcast the user watched.

The step of providing the viewing information to the external device (S500, S600) may be implemented by the communication unit 100 of the viewer rating research system 10.

As described above, according to the viewership rating survey method according to an embodiment of the present invention, a sound source is acquired from the user device 30 of a user watching a broadcast to generate viewing information about which broadcast is being watched. , accurate viewing information can be generated for each user.

In the above, the configuration and features of the present invention have been described based on the embodiments according to the present invention, but the present invention is not limited thereto, and various changes or modifications may be made within the spirit and scope of the present invention. It is obvious to those skilled in the art, and therefore, it is stated that such changes or modifications fall within the scope of the appended patent claims.
